I am developing a custom video component with html5 video tags.
This component can show mp4, ogg and webm videos. I have uploaded a video of each type in the DAM.
When I try to run this component inside of a firefox html5 video tells me "No video with supported format and MIME type found."
This component worked well in CQ5.5 version, is in AEM 5.6 when I have this behaviour. And with MP4 videos is working fine.
I do not know if is because the upload video or that I have to make same configuration in AEM 5.6 for that.
This sounds like a bug - I would open a ticket at:
Smacdonald I have found the mime type video/webm is not registered, I have done by code with the service "org.apache.sling.commons.mime.MimeTypeService" and is working now.
Did anything come of this? I have a similar issue with a DAM asset being returned as application/save.
